Sorry, must've overlooked your post (#110). Here goes...
Actually, according to the numbers you posted in your link...
http://www.truckingboards.com/bb/threads/listen-to-the-anti-union-guys-please.62690/page-5 ...that 1% growth occurred over 4 years...from 2010 to 2014, not 2 years. I'd say 4 years shows a trend of PT starting to level off, wouldn't you agree?
If we go with your "guesstimated" number of 33.54% of the total budget for line haul expenses and 17% for transportation, I could see where PT would seem to be 50% of the total budget compared line haul...but let's also look at the profits these numbers have generated as pointed out by AFlifer.
We could also look at the other side of the coin...it was said back in the early 2000's that it cost (a loss) the company on average $800 per set to run empties down the highway. With that being said, we'd have to assume that if PT was reduced, a large portion of that 17% would result in more empty sets rolling down the road. Now if we factor in the rising cost of fuel, maintenance, wages, bennies, etc...say 12 years later, that cost (loss) would be substantially higher. By looking at this side of the coin, wouldn't it be safe to say that if the PT percentage of the total budget were lower and the line haul cost percentage was higher, the overall profit would also be lower due to the fact of the company losing money by running empties?
Again, I don't like PT's anymore than the next guy, but they are a necessary evil....and if managed properly, they can also be a benefit to the company and all of the employees...IMO.
